COUPLING.

Specification of Letters Patent.

Patented Apr. 4, 1916.

Application filed November 7, 1914. 7 Serial No. 870,867.

To all whom it may concern Be it knownthatI, JULIUS ScHoLL, a citizen of the United States, residing at Everett, in the county of Snohomish and State of WVaslnngton, have invented new and useful Improvements in Couplings, of which the following is a specification.

The present invention relates to improve ments in draw heads for couplings devised for use upon the front end of a locomotive.

One of the objects of the invention is to 7 provide a locomotive engine coupling of a strong, simple, efiicient and. durable construction adapted to permit of the-necessary swinging movement and be readily adjusted to the proper height above the ralls as the locomotive tires wear away or the springs weaken and which can be easily removed and replaced.

In carrying out my invention 1t is my purpose to construct a draw head having centrally arranged therein a transverse lug, the said draw head having openings one of which passes through the lug and the other disposed forward of the lug to receive suitable pins, one of which passes through the coupler as well as through suitable filler or pull plates arranged in the draw head to the opposite sides of the coupler, the other pin passing through buffer plates arranged to the opposite sides of the lug between the filler plates as well as through the said filler plates and wherein the coupler may be properly adjusted in the draw head, the shock and jar incident to the coupling compensated for by the buffer plates and the strain upon the coupler pin of the draw head relieved by the other pin passing through the filler plates, bufier plates and rib.

With the above and other objects in view, the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims.

In the drawings: Figure 1 is a top plan view of a locomotive having its front end provided with my invention, Fig. 2 is a central longitudinal section of the coupler pocket, approximately on the line 2-2 of Fig. 1, Fig. 3 is a horizontal sectional view through the draw head approximately on the line 3-3 of Fig. 2, Fig. 4 is a longitudinal sectional view similar to the device shown in Fig. 2 but illustrating the coupling adjusted within the draw head, Fig. 5 is a perspective view of one of the filler plates, and Fig. 6 is a similar View of one ofthe buffer plates.

Referring now to the drawings in detail, the numeral 1 designates a draw head constructed in accordance with the present invention and which is secured in any desired manner and at a desired position in the front end of the locomotive. The draw head includes a rear plate 2 having longitudinally extending sides 3-3, a bottom connecting wall 4 and atop connecting wall 5. The sides 3 extend at a downward curvature from the upper end of the back 3, and the top 5 being positioned between the sides 3 is horizontally straight and as a consequence a depression or channel is afforded between thetop 5 and the sides 3. Also the back 2 is of a greater width than the draw head between the sides 3, the portions extending beyond the sides being provided with openings 66 through which pass the securing means that retains the draw head upon the locomotive. The draw head is provided with an open face and is further provided, approximately centrally between the top wall 5 and the lower wall 3 with a transversely arranged lug 7, the said lug extending horizontally a distance within the draw head approximately equaling one-half of the length of the said draw head. The lug has an outer arcuate face 8 which is adapted to correspond to the inner rounded end 9 of the shank 10 of the coupler 11. The side walls of the pocket of the draw head diverge outwardly to permit'of a limited swinging movement of the coupler.

Arranged in the pocket of the coupler, to the opposite faces of the shank of the draw head and also to the opposite faces of the lug 7 is a plurality of filler plates 19, and arranged upon the opposite faces of the lug or rib 7 between the said filler plates 19 is a plurality of bufier plates 20. These plates contact with the inner end of the shank of the coupler and are adapted to absorb any shock or jar to which the coupler is subjected. The plates 19 are provided with a pair of spaced openings 2323 and the plates 20 are each provided with an opening 22. The lug 7 is provided with an opening 12 which is adapted to register with openings 1 1 in the upper andlower walls of the draw head, a pin 18 passing through the said openings and through the openings 22 of the plates 19 and 20, thus securing the plates 19 and in the pocket of the draw head. The draw head is provided with registering openings 16 and 17 disposed forward of the lug or rib 7 and which are adapted to aline with the forward openings 23 of the plates 19v and with the coupling pin opening 15 in the shank of the coupler.

The numeral 18 designates a coupler pin which passes through the mentioned forward openings in the draw head,tplates 19 and openings 15 in the shank of the coupler.

By providing the plates 19 the coupler may be properly adjusted vertically in the pocket of the draw head and by providing the plates 20 the shock and jar to which the coupler may be subjected will be partially absorbed; The arrangement of the pins 18 and 13 and their connection with the plates materiallyadd to the strength of the structure, the pin 13 absorbing or compensating for an amount of strain to which the coupler pin 18 would ordinarily be subjected.

copies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents.

Having thus described the invention, what I claim is:

A draw head for the coupler of a locomotive including a pocket having its side walls flared outwardly and provided with a central transverse lug at the rear thereof and the said pocket adapted to receive the shank of the coupler, filler plates in the pocket and upon the opposite faces of the shank of the coupler, bull'er plates upon the opposite:

faces of the lug betweenthe mentioned filler plates and contacting 'withthe inner endsof the coupler shank, a pinpassing through openings in the draw head, the filler and buffer plates and through the rib of .the

draw head, and a second pin'passing through openings in the drawhead, the filler and the shank of the coupler.
